The story

Mahendra Chawla, personal assistant to godman Asaram Bapu, was shot by gunmen in his house on 13 May.

Asaram Bapu and his son Narayan Sai are in jail. Two sisters have accused them of rape. This is called the Surat rape case.

Shocking facts

Chawla is the sixth eyewitness to have been attacked. Two are dead. All of them were close associates of Asaram Bapu.

One of two former aides was gunned down. The other was knifed but survived. Two others were shot at, one fatally. One was knifed. One doused with acid.

The background

Two sisters accused Asaram Bapu and his son of rape in October 2013.

The younger sister accused Narayan Sai of raping her from \'02-\'05. The elder accused Asaram of raping her from \'97-\'06.

Other accusations

Two 10-year old boys - Dipesh and Abhishek Vaghela - found dead 1.5 km from Asaram\'s Motera Ashram. Had joined the ashram barely a month earlier.

Body of one boy found slit from throat to waist; internal organs missing.

The other boy was missing an arm. The father says men were sent to intimidate him.

Asaram calls a 16 year-old girl to his room alone. On the pretext of driving evil spirits from her body, he sexually assaults her repeatedly.

Asaram is also accused of land grabbing in different states.In February 2009, Gujarat Assembly admits his ashram encroached on 16 acres of prime estate.

The fear

A senior journalist says everyone who spoke against Asaram or his son is being attacked.

One aide was shot dead two days after speaking to the journalist.

On 13 May, Mahendra Chawla was shot at by unidentified gunmen inside his house in Panipat. This makes him the sixth key witness to be attacked in the high profile rape cases against godman Asaram Bapu and his son Narayan Sai. Two of those attacked are dead.

There was a time, eyewitnesses recall, when busy streets in Gujarat were deserted as channels began telecasting the sermons of Asaram Bapu. One report estimated two crore people to be following the spiritual guru, and his empire to be worth Rs 5,000 crore.

The background

There was a time when he got away with spraying millions of gallons of water on his followers during Holi in draught-hit Maharashtra, with blaming the victim of the infamous December 16 gang rape for her fate, and running hundreds of ashrams spread over thousands of acres of encroached public land.

Senior politicians like LK Advani and Digvijay Singh were photographed in his vicinity and many more were reported to be ardent followers. But that was then.

Asaram Bapu and his son Narayan Sai are behind bars these days. They've got almost no ashrams left. Asaram's leftover following seems to be the 21,000 people that have liked his Facebook page. What remains is a web page - ashramnews.org - last updated two years ago, devoted to proving him innocent.

The 74-year-old guru has been in a Jodhpur jail since August 2013 for allegedly raping a 16-year-old schoolgirl at his ashram earlier that year.

Two months later he, along with his son Narayan, were booked for the alleged rape of two sisters at their ashram in Surat, Gujarat.

The horror

Asaram's spiritual career began in the 1960s. Ostensibly, the trouble only began in 2008 after the deaths of two 10-year-old cousins, Abhishek and Dipesh Vaghela, at his Motera ashram in Gujarat.

Praful Vaghela, father of Dipesh, still remembers the sight of his son's body. "From the throat down, there was a slit till his waist and all the internal organs were missing. There were burn marks on both the children and their clothes were missing." Dipesh was his only child.

Praful had entrusted him to Asaram Bapu on 1 June 2008 - exactly a month before the bodies of his son and nephew were found 1.5 kilometres from the Motera ashram - because he thought the gurukul system was the best model of education for children.

"I never thought of Asaram as a god and was never infatuated by him. It was only the education of my child that I was concerned about. Some time in between I went to the ashram and met the kids. There heads were tonsured and there was a tilak on their foreheads, I didn't like it but I was told that's how things were run there," Praful says.

While Asaram Bapu is in jail with his son for rape, someone's trying to kill all the witnesses

According to Praful, who works as a labourer near Motera, immediately after the bodies were found, several armed men approached him to intimidate him into submission.

"They told me not to even think about lodging an FIR in the case. Even mentioning the death of my son would have dire consequences, I was told. Asaram Bapu, those days, was India's uncrowned king. For a long time, despite my appeals, the police did not register the FIR," says Praful.

The Gujarat Criminal Investigation Department finally filed a chargesheet against seven office-bearers at Asaram's ashram in September 2012. But Asaram managed to stay out of jail in this case.

Praful still doesn't know the reason for the brutal murder of his only son but, in his fight for justice, he has come across several other people whose allegations against Asaram Bapu range from sexual misdemeanours, macabre tantric rituals, murder and intimidation.

The accusations

The most concrete allegation against Asaram Bapu, however, was made in August 2013 by a 16-year-old inmate of his Chhindwara ashram in Madhya Pradesh. The teenager accused him of sexually assaulting her at a farmhouse in Jodhpur on the pretext of treating her.

Asaram had reportedly demanded a private interview with the girl, who studied at Asaram's ashram and stayed in a girls' hostel there, to drive evil spirits from her body and sexually assaulted her repeatedly.

Mahendra Chawla is the latest to have been killed for speaking against Asaram in court

He was booked by the Delhi and Jodhpur police and arrested in September. The case drove fervent followers to scepticism if not outright hostility.

Asaram's lawyer, leading advocate Ram Jethmalani, defended his client by claiming that the girl was suffering from a disease which made her want to meet men alone.

More reports of sexual violence, this time also against the godman's son, were made a couple of months later.

In October 2013, two sisters, also inmates of his ashram, alleged that the father-son duo had raped them at their Gujarat ashram.

The younger sister alleged Narayan Sai had raped her repeatedly between 2002 and 2005 at Asaram's ashram in Surat, and the elder sister leveled allegations against Asaram Bapu for raping her between 1997 and 2006 while she was living at his ashram on the outskirts of Ahmedabad.

Asaram's lawyer Ram Jethmalani argued that the accuser had a disease that made her want to meet men alone

Based on this, both Asaram Bapu and Narayan Sai were booked in October 2013. This case, commonly referred to as the Surat rape case, has proved to be the most damning indictment for the two supposed spiritual guides.

Asaram's defence counsel, BM Gupta, claims the case is an attempt to frame his clients falsely. "Both Asaram Bapuji and his son have been deliberately framed in these cases. It is notable that FIR was lodged against Bapuji 12 years after the offence was committed and against Narayan Sai 11 years later. Charges of rape and unnatural offences have been filed against my clients. We are challenging the allegation of unnatural offence at the admission stage itself."

The fear

Ever since the case was reported nearly two years ago, it has been trapped in an atmosphere of intense fear.

Nobody related to the case speaks or reveals their identity anymore for the fear of being taken out, as is generally believed by those close to the godman. A senior journalist, who covered the case when it was the focus of the nation, explained the intense pressure he went through.

"There was a climate of fear around the case from the beginning - a sense that anyone who spoke to the media against Asaram or his son was taken out. I had this personal experience of speaking to Amrut Prajapati, one of his personal physicians who had turned against him as a witness, and quoting him in a story. Two days later, he was shot at from close range and a fortnight later, he succumbed to his wounds," said the journalist, not willing to be named.

The killings

Mahendra Chawla, who was Asaram's personal assistant from 2001 to 2005 in Panipat, is the latest witness to be attacked. Chawla had made startling revelations about the spiritual guru in an interview to a television channel.

According to him, Asaram used to select girls by throwing fruits or prasad at them or even by pointing torch light at them. Chawla also said that Asaram was addicted to opium and an NRI used to supply opium to him. Chawla survived the murder attempt and is currently recovering in a hospital.

Earlier this year, on 13 January, Akhil Gupta, a dairy owner who used to serve as Asaram's cook, was was shot dead in Muzaffarnagar, the second witness to have been killed. He is believed to have given the police some incriminating evidence against Asaram Bapu.

The first witness to be murdered was Vaid Amrut Prajapati, Asaram's former aide and an Ayurveda expert. He was shot dead in Ahmedabad in May 2014.

Amrut Prajapati, Asaram's former aide, was the first of the witnesses to have been killed.

He had worked with Asaram for about 15 years till August 2005. In an interview before his death, he claimed he had been developing Ayurvedic medicines for the ashram, which were often adulterated on Asaram's directions.

In the same interview, Prajapati claimed to have walked in on one of Asaram's intimate sessions with a woman, following which he was scared out of the ashram.

Three years later, he deposed as a witness in the case of the mysterious death of two boys in 2008, and shed light on alleged tantric practices at the ashram.

In the case of Dinesh Balchandani, a textile trader, two men on a motorcycle had tried to douse him in acid in Surat in March 2014.

Rakesh Patel was the first victim in this series of apparently closely coordinated attacks on witnesses. One of the key prosecution witnesses and husband of one of the two women who had alleged rape against the godman and his son, he was almost knifed to death on 28 February 2014 by motorcycle-borne assailants.

As the trend later emerged, Patel was retrospectively seen to be the first victim for speaking against the influential guru. The common thread binding the five victims after him is that they shared evidence and openly denounced Asaram in connection with the Surat rape case.

Asaram was one of the first spiritual television phenomenons in India. He doesn't seem to have lost his capacity for on-camera performance.

"Duniyan mein sabhi hamle main hi karwata hoon (I am responsible for all the attacks in this world)," he sarcastically remarked while being taken to court in Rajasthan's Jodhpur.

Both Asaram and his son are lodged in a prison in Rajasthan. The witness deaths should pose hard new questions for them.

He hasn't been to journalism school, as evident by his refusal to end articles with 'ENDS' or 'EOM'. Principal correspondent at Catch, Suhas studied engineering and wrote code for a living before moving to writing mystery-shrouded-pall-of-gloom crime stories. On being accepted as an intern at Livemint in 2010, he etched PRESS onto his scooter. Some more bylines followed in Hindustan Times, Times of India and Mail Today.
